In Lessons 3 and 5 of this course, you'll use a virtual machine (VM) to run a database server and a web app that uses it. The VM is a Linux server system that runs on top of your own computer. You can share files easily between your computer and the VM.
We're using the Vagrant software to configure and manage the VM. Here are the tools you'll need to install to get it running:
If you don't already have Git installed, download Git from git-scm.com. Install the version for your operating system.
On Windows, Git will provide you with a Unix-style terminal and shell (Git Bash).
(On Mac or Linux systems you can use the regular terminal program.)
You will need Git to install the configuration for the VM. If you'd like to learn more about Git, take a look at our course about Git and Github.
VirtualBox is the software that actually runs the VM. You can download it from virtualbox.org, here. Install the platform package for your operating system. You do not need the extension pack or the SDK.
Vagrant is the software that configures the VM and lets you share files between your host computer and the VM's filesystem. You can download it from vagrantup.com. Install the version for your operating system.
Windows: Use the Git Bash program (installed with Git) to get a Unix-style terminal.
Other systems: Use your favorite terminal program.
From the terminal, run:
git clone http://github.com/udacity/fullstack-nanodegree-vm fullstack
This will give you a directory named fullstack.
Using the terminal, change directory to fullstack/vagrant (cd fullstack/vagrant), then type vagrant up to launch your virtual machine.
Once it is up and running, type vagrant ssh to log into it. This will log your terminal in to the virtual machine, and you'll get a Linux shell prompt. When you want to log out, type exit at the shell prompt. To turn the virtual machine off (without deleting anything), type vagrant halt. If you do this, you'll need to run vagrant up again before you can log into it.
Files installed for this class are located in the /vagrant directory inside the virtual machine. Everything here is automatically shared with the vagrant directory inside the fullstack directory on your computer. Any code files you save into that directory from your favorite text editor will be automatically available in the VM.
If you’d like to see what was installed in the VM, look in /vagrant/pg_config.sh.
In this class you will mostly be running your work in Python from the command line. In addition you’ll use the psql program to interact with the PostgreSQL database.
To connect psql to the forum database for Lesson 3, type psql forum at the command line. To exit psql, type \q or Control-D (^D).
